In the Linux kernel, the following vulnerability has been resolved:
comedi: comedi_8255: Correct error in subdevice initialization
The refactoring done in commit 5c57b1ccecc7 ("comedi: comedi_8255: Rework
subdevice initialization functions") to the initialization of the io
field of struct subdev_8255_private broke all cards using the
drivers/comedi/drivers/comedi_8255.c module.
Prior to 5c57b1ccecc7, __subdev_8255_init() initialized the io field
in the newly allocated struct subdev_8255_private to the non-NULL
callback given to the function, otherwise it used a flag parameter to
select between subdev_8255_mmio and subdev_8255_io. The refactoring
removed that logic and the flag, as subdev_8255_mm_init() and
subdev_8255_io_init() now explicitly pass subdev_8255_mmio and
subdev_8255_io respectively to __subdev_8255_init(), only
__subdev_8255_init() never sets spriv->io to the supplied
callback. That spriv->io is NULL leads to a later BUG:
